Fully Dedicated Installation
The fully dedicated installation draws stale air from specific
points in the house and delivers fresh air to specific loca-
tions of the house. This system is not connected to an air
handler/furnace (see figures 12 and 13).
Figure 12. Fully Dedicated System
Stale air ducts should be installed in areas of the home
where the poorest indoor air quality exists (bathrooms and
kitchen). Each location with a stale air duct should have a
timer to initiate high−speed ventilation. (Refer to Optional
Timers" on page 12.)
Fresh air ducts should be installed to all bedrooms and liv-
ing areas, excluding bathrooms, kitchen, and utility areas.
Grilles should be located high on a wall or in ceiling loca-
tions. Grilles that diffuse the air comfortably are recom-
mended. (Refer to Grilles on page 19.) Special care should
be taken in locating grilles if the floor is the only option
available. Areas such as under baseboard heaters will help
to temper the air.
Optional inline duct heaters are available for mounting in
the supply air duct work to add heat if required.
